INSULATOR.

Application filed February 25, 1915.

T 0 all whom it may concern:

Be it known that I, LOREN STAHL, a citizen of the United States,residing at Carey, in the county of IVyandot and State of Ohio, haveinvented certain new and useful Improvements in Insulators, of which thefollowing is a specification.

This invention relates to insulators of the class known generally ascleats, for use in stringing and maintaining current carrying wires 1nsuitably spaced relation with themselves and with the attaching walls.

The main object of the invention resides in the provision of a cleatwherein its sections are so formed that there is practically nopossibility of them becoming disengaged when once they are in theirapplied position. It frequently happens that the various sectionsforming the cleat become dislodged or shifted in such manner that thewire or wires they are intended to support may also become dislodged.

A further object of the invention resides in so forming the structurethat it is practr cally impossible for the current carrying wire orwires to so shift themselves that they come into engagement with theattaching nails or screws used for holding the insulator sections inposition.

Other objects of the invention will appear after a further detaileddescription of the accompanying sheet of drawings representing thepreferred embodiment of my in vention.

In these drawings, similar characters of reference designatecorresponding parts, and, Figure 1 represents a view in side elevationof the cleat, Fig. 2 is a top plan view of one of the sections, thesections being duplicates of each other, Fig. 3 is a side elevation ofone of the sections shown detached, and, Fig. 4 is a detail view inperspective of one of the sections.

In the drawings, the cleat as a whole is represented by two similarlyformed sections designated 1, these sections being formed so as to beinterchangeable in order to render the selection of the cooperatingparts to form a complete cleat, more handy. Each of these sections isprovided with a pair of outstanding lugs 2, these lugs being preferablyV-shaped in contour and extending transversely across each sectionapproximately half its width, as shown. Each section is also providedwith a pair of grooves Specification of Letters Patent.

3 similar in shape to the lugs 2 in order that they may receive theopposing lugs of the other section in interfitting relation, thesegrooves, therefore, naturally forming the other half of the widthportions of each section not occupied by the lugs 2. This arrangemcnt oflugs and grooves prevents shifting of the insulator sections either in alongitudinal or transverse direction. Each section is also provided witha pair of nail attaching holes shown at at, these holes being so locatedthat they pass centrally through the intersections of the lugs andgrooves of each section, this arrangement being followed to permit thecomplemental sections being made in true interchangeable order. Also, itis desirable to place these holes at the farthest possible pointpracticable from the transversely extending wire receiving grooves 5 andI, therefore, locate these to pass through that side of the lugs 2 andgrooves 3 nearest the section end faces as is indicated. Thus, it willappear that it is practically impossible for the wire to come intocontact with the attaching nails even should the sections be so mountedthat there would be a limited play between them.

In the use of the term nail, it is understood that all such structuresas are used for attaching cleats or insulators, are included.

It will thus be apparent that I have provided an insulator of peculiarconstruction so arranged that the various sections are prevented againstshifting under any ordinary conditions. Also, these sections are madeinterchangeable in nature, which run ders their selection in usecomparatively easy. I desirably provide only one wire receiving groovefor each section, this groove being located between the two nailreceiving holes, but it is to be understood that if desired two or morewire receiving grooves may be provided.

What I claim, is:

1. An insulator cleat comprising complemental superposed sections, eachsection being provided with a pair of depending lugs extendingtransversely across the section approximately half its width, the lugsof each section beinglocated on opposite sides of the longitudinalcenter line of the section, each section being formed with a pair ofgrooves shaped to receive the opposing lugs of the other sectionv ininterfitting relation, said grooves forming the other half of the width.portions of said sections, and wire receiving formations between thelugs of each section.

2. An insulator cleat comprising comple- -mentalsuperposed sections,each section being provided with a pair of depending lugs extendingtransversely across the section approximately half its width, the lugsof each section being located on opposite sides of the longitudinalcenter line of the section, each section being formed with a pair ofgrooves shaped to receive the opposing lugs of the other section ininterfitting relation, said grooves forming the other half of the widthportions of said sections, and wire receiving formations between thelugs of each section, said sections being also formed with attachingnail holes passing centrally through the intersections of the lugs andgrooves of each section on the sides farthest from said wire receivingformations.

In testimony whereof I aflix my signature in presence of two witnesses.
